We completed a project 12 months ago, £120k to replace most of the pumps in a hospital. Measurement and verification complete. They have saved £140k in electricity in year one
Sorry but newer is often better
On paper anything can look good.

Not to derail this thread, but it's confirmed, hence the measurements. If it doesn't work we don't get paid
I know it's a lost cause on this forum so thank you and goodnight
To the OP, good advice in this thread. At 25 years I wouldn't even bother with the valves and just replace the lot

I'd suggest the quality of manufacturing is at a different levels on an industrial pump in a hospital and the cheapest domestic pump on eBay.
Those old grundfos pumps run for ever, I've a pair here that have at least over 23 years service each on them.
I suspect you wouldn't see the same level of quality in a modern domestic CH pump. But I would perhaps expect that level of reliability from an industrial pump costing thousands...
Myson used to be manufactured here locally, but I believe that has all gone now.
I know we're way off topic... and a lot of stuff is worse these days.....
but manufacturing has moved on so far in 20 years (and massively if you go back further) that it's much easier/cheaper to make a high quality product than it was back then
actually... I wonder if that's one of the reasons behind the drop in quality.... things are so much easier/cheaper to make now quality isn't taken so seriously?
also a bit of confirmation bias of course, maybe they weren't much better back then but the rubbish ones died 20years ago and the small % or freakishly good ones kept running making us think they all have?

Going back to topic
I have just changed the exact same pump but mine was probably only 20 years old
Good luck on yours, my valves worked but I could only undo one of the large nuts the other was just too frozen to manage despite my girt big spanner. I even took the motor off the head so that I could clamp the head of the unit to get more force on the nut
Moral of this story. Make sure you have replacement ball valves available before starting the change
